Upgrade to the latest Firmware version 2.75.69 (20211110)

Please note

1 This firmware can only run on WEM3080 series product(WEM3080,and WEM3080T), not on WEM3162.

2 For WEM3080 series, only the firmware version of 1.70.x and later can be upgraded to this version. Please do not upgrade your firmware if the version is earlier than 1.70.1.

3 Please keep the power and do not close the browser during the upgrading process. Otherwise the product will not be startup again ( The product need to be send back to factory).

 

If the customer encounters the situation that the device cannot operate normally due to the failure of firmware upgrade (we have never encountered this situation, but our customer has indeed fed back such problem to us before), we will not bear any responsibility.

Therefore, please carefully decide whether to upgrade this firmware

Latest update of IAMMETER (MQTT, Data Upload Interval Setting, Net Metering Mode)

Latest firmware: 2.75.69

SHA256: 494BFE9197A2174CF9257BE76D5A2B3D49F7D13BFE25685FBA6A53A9D6FD6859

 

IAMMETER has been upgraded recently, including

  1. Support uploading meter's data to IAMMETER-cloud and third party MQTT server using MOTT
  2. Support setting meter's data upload interval by users
  3. Support setting WEM3080T (3-phase WiFi energy meter) to net metering mode

 

 

 

1. MQTT

1.1 Upload data to IAMMETER-cloud using MQTT

1.1.1 Configuration

Currently, you can set MQTT server configuration on configuration web page.

image-20210722155047592

Run Mode: TCP

TCP Address: mqtt://mqtt.iammeter.com:1883

1.1.2 The benefit of uploading data to IAMMETER-cloud using MQTT

In this case, the data upload interval can be set by users. The minimum data upload interval can be set as 6 seconds.

Please note that the minimum data storage interval on IAMMETER-cloud is 1 minute, which means that even the data upload interval is set less than 1 minute (6 seconds for example), IAMMETER-cloud also stores the data in every 1 minute. However, you can subscribe the related MQTT topic, and then the subscribing result refreshes in according with the data upload interval (6 seconds) preset by you.

For how to subscribe the topic from IAMMETER-cloud, please refer to https://imeter.club/topic/20

1.2 Upload data to third-party MQTT server

Authentication mode: ClientID without password or Anonymous

Topic :device/sn/realtime

2 Change the data upload interval

To understand how the data upload interval setting works,please click here

 

2.1 Set the data upload interval

You can change the data upload interval by local API as below:

http://ip/api/uploadinterval=N

Method: HTTP get

N: The parameter to calculate the data upload interval, which can only be natural numbers. The formula to calculate the data upload interval (T) is,

T = (N+1) * 6

The unit of T is seconds.

For example, as shown in below picture, if we set the N as 1, then the uploading data interval is

T=(1+1) * 6 = 12

So the data uploading interval is set as 12 seconds.

2.2 Get the data upload interval

 

After setting the data upload interval ,you can test it using below API.

http://ip/api/wifidata

Method: HTTP get

3. Set WEM3080T(3-phase WiFi energy meter ) to net metering mode

I understand your concern.
But now, the MQTT is just an option for some amateur that can be integrated into their own service easily.
We have not considered clearly whether it will affect our current service if we introduced extra authentication in mqtt.
If you are worried about the data security in MQTT publishing, you can consider the TLS method,

This is a video tutorial about how to upload the energy data of the energy meter to a third-party TLS server.

Hi:

This post is mainly for the introduction of the latest firmware.
Please post your question in a new thread. It will be more clear and easy to discuss.

Hello!I'm very sorry for my silence, but right after my post i've been sick for a while, and after that i kinda forgot this problem. I remembered today when i received my monthly consumprion report... with all ZEROES? I have zero kWh consumption for each day for whole september. Even my current consumption graph on overview page (power, grid consumption) show nothing - empty graph, just current power. Going back from net metering to normal and current consumption show graph is populated with da

Hello!

I'm very sorry for my silence, but right after my post i've been sick for a while, and after that i kinda forgot this problem. I remembered today when i received my monthly consumprion report... with all ZEROES? I have zero kWh consumption for each day for whole september. Even my current consumption graph on overview page (power, grid consumption) show nothing - empty graph, just current power. Going back from net metering to normal and current consumption show graph is populated with data again, but it seems that september history is gone. 

So, for now i'm gonna stay at "normal metering". History is more important for me than current data send every 6 seconds. And,BTW... i double-checked: i have data upload interval correctly set to zero (which means 6 seconds). I didn't check MQTT though, because of the problem, mentioned above.

Hi:

Please try to read the upload interval and check whether it had been set to zero as you wanted.

refer to this:

   2.2 Get the data upload interval


If it had been proved set to zero, you can subscribe this mqtt data of this SN and check whether the data refresh every 6 seconds.

refer to https://imeter.club/topic/20#subscribe-real-time-data


Strange... doesn't work here...I've done all exactly as stated: - updated  FW to latest (ATV2.75.66@MX1290)- entered mqtt address  (mqtt://mqtt.iammeter.com:1883)-entered zero for 6 seconds (http://192.168.x.x/api/uploadinterval=0)- set to net metering mode in my iammeter webpagebut on my "overview" page data still updates only once per minute, and even this updates only if i click on "overview" each time. On your youtube video data is automatically refresed... So, what did i miss

Strange... doesn't work here...

I've done all exactly as stated: 

- updated  FW to latest (ATV2.75.66@MX1290)
- entered mqtt address  (mqtt://mqtt.iammeter.com:1883)
-entered zero for 6 seconds (http://192.168.x.x/api/uploadinterval=0)
- set to net metering mode in my iammeter webpage

but on my "overview" page data still updates only once per minute, and even this updates only if i click on "overview" each time. On your youtube video data is automatically refresed... So, what did i miss?

My meter is 3-phase model.

Hi:

Make the upload interval less than 6 seconds will bring some problems in our current logic, when we find a better method to solve these problems we will consider shorter this 6seconds interval.

Hello,Thank you for the update, seems to work fine. Would it be possible to increase the update interval to 1 per second?I'm not interested in the energy values, but mainly the power values to regulate other stuff.Thank you!

Thank you!


we would provide the detailed change list in next upgrading.

Could you show what was history of upgrade firmware and what was changed added?

Yes, same firmware.

hello aigain, no i have a new one with 1 phase ATV1.75.32@MX1290is this the same Firmware ?
